Key Financial Metrics

Material Changes vs. Prior Period

• Increased Net Loss: Net loss increased by approximately $52.5 million (31%) year-over-year, driven primarily by higher R&D expenses.
• R&D Expense Surge: R&D expenses rose by $44.5 million. Key drivers included a one-time $20.0 million upfront license fee paid to Genrix for the velinotamig asset, increased clinical development costs ($21.9 million), and higher personnel costs ($8.2 million).
• Investment Portfolio Shift: Long-term investments decreased significantly from $204.4 million to $58.3 million due to maturities of marketable securities ($416.6 million proceeds) partially offset by new purchases ($236.5 million).
• Program Discontinuations: The company discontinued development of CLN-619 (gynecological cancers, NSCLC, multiple myeloma) and CLN-617 (solid tumors) in 2025 based on emerging clinical data not meeting internal thresholds.

Guidance, Outlook, and Management Commentary

Liquidity Outlook: Management expects current cash, cash equivalents, and investments ($439.0 million total) to be sufficient to fund operations into 2029. No debt financing is currently outstanding.

Pipeline Progress:

• Zipalertinib (Oncology): In collaboration with Taiho, a New Drug Application (NDA) was submitted in February 2026 for accelerated approval in EGFR ex20ins NSCLC. Cullinan is eligible for up to $130 million in milestone payments and 50% of U.S. pre-tax profits.
• CLN-978 (Immunology): Phase 1 trials are ongoing in SLE, RA, and Sjögren's disease. Initial data for SLE and RA is expected in Q2 2026.
• CLN-049 (Oncology): Phase 1 dose escalation in AML/MDS is ongoing. Dose expansion cohorts are planned for Q2 2026.
• Velinotamig (Immunology): Licensed from Genrix; Phase 1 trial in China is enrolling for autoimmune diseases.

Risks: The company faces significant risks related to clinical trial outcomes, regulatory approval timelines, patient enrollment challenges, and the need for substantial additional capital if development costs exceed current estimates. The company relies heavily on third-party manufacturers and collaborators.

Key Facts for Investor Verification

• Cash Runway: Verify the sufficiency of the $439 million cash position to fund operations through 2029, considering the high burn rate (~$176 million operating cash outflow in 2025).
• Zipalertinib Milestones: Confirm the status of the NDA submission with the FDA and the specific regulatory milestones required to trigger the potential $130 million in payments from Taiho.
• Genrix License Terms: Review the specific clinical and regulatory milestones associated with the $292 million potential milestone payments and royalty obligations for velinotamig.
• Clinical Data Readouts: Monitor the Q2 2026 data readouts for CLN-978 (SLE/RA) and the Q2 2026 initiation of CLN-049 dose expansion, as these are critical value inflection points.
• Discontinued Programs: Assess the impact of the discontinuation of CLN-619 and CLN-617 on the overall pipeline strategy and resource reallocation.
